A similar change is required on the alpha. Could someone check that
the following patch fixes the problem with 16k/2k filesystems on
the alpha? Boot1 would fail to load correctly any files larger than
192k, so the bug generally only affected -current where /boot/loader
is greater than that size, or the case where you load a kernel
directly from boot1.
